Answer 2

使用Java邮件用户创建后发送电子邮件

final String username = "admin@gmail.com"; 
     final String password = "password"; 

     Properties props = new Properties(); 
     props.put("mail.smtp.auth", "true"); 
     props.put("mail.smtp.starttls.enable", "true"); 
     props.put("mail.smtp.host", "smtp.gmail.com"); 
     props.put("mail.smtp.port", "587"); 

     Session session = Session.getInstance(props, 
      new javax.mail.Authenticator() { 
      protected PasswordAuthentication getPasswordAuthentication() { 
       return new PasswordAuthentication(username, password); 
      } 
      }); 

     try { 

      Message message = new MimeMessage(session); 
      message.setFrom(new InternetAddress("from-email@gmail.com")); 
      message.setRecipients(Message.RecipientType.TO, 
       InternetAddress.parse("to-email@gmail.com")); 
      message.setSubject("Testing Subject"); 
      message.setText("New user created"); 
      Transport.send(message); 
     } catch (MessagingException e) { 
      throw new RuntimeException(e); 
     } 
    }
